Implementation of Software Controlled Radio for Long Range Communication with High Data Rate and Optimal Capacity

In the recent past, the software controlled radio
(SCR) plays major role in wireless communication for long range communication. The wireless communication based SCR has communicated the information for a short distance due to the low data rate and poor capacity of frequency modulation scheme. The OFDM technology has adapted the SCR for providing elimination of error due to the communication of information for long range. The synchronization error is highly reduced by applying the matched filter between transmitter and receiver antennas. The distributed antenna system is implemented with OFDM SCR communication for information transfer through the wireless channels. The AWGN, Rayleigh and Rician fading channels are used for long range communication of SCR information. The number of base stations (BS) is reduced by finding the energy efficient transmission using SCR for long range communication. The heuristic approach is used for improving the capacity of the
SCR system in terms of Mbps. The Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI) are reduced by applying the cyclic prefix of OFDM by applying an Advanced Per Subcarrier Channel Equalizer (APSCE). The equalizer technique is used to provide reduced Bit Error Rate (BER) with improved Signal to Noise Ratio (SNR)
